Inductance & Mutual Inductance — from Flux Linkage

Inside this lesson

Define self-inductance L as the ratio of flux linkage to current: L = Λ/I = NΦ/I
Explain why inductance is a geometric property, independent of current
Define mutual inductance M between two coils as M = Λ₂₁/I₁
Recognize that a changing current in one coil will induce an EMF in another via M — a preview of Faraday's law
